Abstract (en)

[origin: WO2019192990A1] The use of an organic compound as cleavable additive, preferably as cleavable surfactant, in the modification and/or treatment of at least one surface of a semiconductor substrate is described. Moreover, it is described a method of making a semiconductor substrate, comprising contacting at least one surface thereof with an organic compound, or with a composition comprising it, to treat or modify said surface, cleaving said organic compound into a set of fragments and removing said set of fragments from the contacted surface. More in particular, a method of cleaning or rinsing a semiconductor substrate or an intermediate semiconductor substrate is described. In addition, a compound is described which is suitable for the uses and methods pointed out above and which preferably is a cleavable surfactant.
